CAR-TRUCK LLPEGIFICATION forming part of Letters Patent No. 314,402, dated March 24, 1885.

Application tiled January 17, 1885. (No model.)

I all whom t may 00u/cern:

Be it known that l, JEFFERSON Davis TRAMMELL, a citizen of the United States, residing at Auburn, in the county of Lee and State of Alabama, have invented a new and useful Improvement in Railway Systems, of which the following is a description.

This invention relates to car-trucks and cartracks adapted therefor; and it has for its object to economize the construction of short-line railroad and a portion of a ear according tol my invention. Fig. 2 is a plan view ot' the same without the ear-body. Fig. 8 is atransverse vertical section ofthe track, and Fig. 4 is a detail ofthe track at sidings, yards, &c.

A represents the body of a car or wagon; B, the holsters; C, the filth-wheel; D, the axle, and E the car-Wheels journaled to revolve on the axle. The ear is mounted both fore and aft on its axles by means of fifth-wheel C, so

that the axles may both turn thereon in order,

that they remain coincident with the radius of any curve on which the car is traveling, thereby maintaining the wheels in line with the track.

To direct the rear axlealways into the position just described, I provide it with a reach, F, connected with the king-bolt of the forward fth-wheel, C, and I rigidly brace the rear axle to the reach by means of hounds G. By this means the rear truck takes its lead and direction from the forward truck. The forward truck is provided with an independent leadingwheel, H, journaled in a tongue, I, and having two iianges to keep it upon a central track, J. This tongue is bifurcated at its forward end to receive the wheel H, and at its rear end for the purpose of forming a bracing attachment to the forward axle, D. This attachment is such as to permit a little vertical play of the tongue I without rocking the axle.

K is a link or reach freely connecting two cars by their king-bolts, so as to permit each car to follow the lead ot' its own wheel H.

The Wheels E, on which the car is mounted, have broad flat rims without danges, and the side traeks,L,are also broad and flat,and need not stand above the surface of the ground. In fact it is designed that the side tracks may be done away with on ground which is hard enough to support the engine and loaded cars on the broad-rimmed wheels described; but the guiderail J is to be laid throughout the line of the road. Crossties M support all the raiis, and being secured thereto,as usual,they

keep the rails at proper distances apart. In any portion of the road where the side rails may be dispensed with the cross-ties M should be too short to enter the paths ofthe side wheels,E, as shown at the left in Fig. 4t. The caster-wheel H is to be secured to the forward truck of the engine, to operate in the same manner, as on the cars described, and the drive-wheels ot' the engine may be con structed and operated in any usual manner, not requiring iianges. There short turns and backings are to be made by the cars on sid ings and yards and at stations, an eXtra set of side rails, N, Fig. 4, may be placed hoppershaped, and be provided with ilanges O for a suiiicient distance to guide the side wheels upon the track.' The rails of this road may be made of iron where the amount ot'traiiic will warrant it, or they may be mere straps ot' iron spiked upon timbers, or the side rails may be logs flattened on the upper side. This makes a Very cheap and eliicient railway system for mining and timber regions and for general' short branch roads. Either one or both side wheels may be mounted to turn on the axle. It' only one wheel is loose, the axle will be journaled in bearings in the truck.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The combination, in a railway system,0f cars mounted upon trucks, both fore a-nd aft, by means of iiftlrwheels, side wheels to each truck free to revolve independently of each other, a tongue extending forward of the forward truck, a two-tlauged wheel jourualed in the forward end of the tongue, a reach conneeting the rear truck with the king-bolt of the forward truck, two wide flat-topped side rails and a narrow central rail secured upon the rOa-d,a11 substantially as described, for the cross-timbers shorter than the space between lo purpose speeied. the side truck-wheels lying' inthe groundand 2. The combination of cars mounted on l supporting the track, substantially as shown trucks by means of fifth-Wheels, the trucks and described. havin@ broad-rimmed flat-faced su ortinof- 5 wheels, a tonge extending forwa) of tle JEFFERSON D TRAMMELL' Car, a two-flanged guide-Wheel journaled in Witnesses: the tongue, a single track of a width to enter W. C. DOWDELL, between the flanges of the guide-wheel, and J. J. PADGETT.
